Title: Improvements in the manufacture and production of dyestuffs of the phthalocyanine series
IPC: C09B47/10
Filed: 1938-05-17
Abstract: 514,857. Dyes and lakes. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). May 17, 1938, No. 14732. [Classes 2 (iii) and 15 (ii)] Water-soluble dyestuffs of the phthalocyanine series containing halogen are manufactured by treating phthalocyanine sulphonic acids containing at least three sulphonic acid groups, or salts thereof, with halogenating agents for such a length of time that the final products are still soluble in water. Suitable starting materials are obtainable by treating metal-free or metal-containing, e.g., copper, nickel or aluminium, phthalocyanines with oleum or chlorsulphonic acid or both, and they may contain sulphochloride groups as well as sulphonic groups. The halogenation may be effected with chlorine, bromine or sulphuryl chloride, if desired under pressure, and preferably in the presence of a solvent or diluent, e.g., trichloracetic acid, commercial trichlorobenzene or phthalic anhydride, or a melt of anhydrous aluminium halide and alkali halide. The products dye vegetable and animal fibres, e.g., cotton, silk or wool, or regenerated cellulose, blue-green to green shades, and yield colour lakes with metal salts usually employed for the production of colour lakes from colouring matters containing sulphonic groups, e.g., salts of alkaline-earth metals or of zinc, manganese or aluminium. In examples: (1) a sulphonic acid obtained by treating copper phthalocyanine with oleum is introduced into a melt of aluminium chloride and sodium chloride, and chlorine is passed in at 150‹ C. ; (2) a sulphonic acid obtained by treating copper phthalocyanine with chlorosulphonic acid is similarly chlorinated; (3) a sulphonic acid obtained by treating nickel phthalocyanine with chlorosulphonic acid is similarly chlorinated ; (4) a sulphonic acid obtained by treating aluminium phthalocyanine with chlorsulphonic acid is similarly chlorinated ; (5) a copper phthalocyanine tetrasulphonic acid is introduced into a melt of aluminium chloride and sodium chloride, and bromine or iodine is added ; (6) copper phthalocyanine tetrasulphonic acid is introduced intoa melt of phthalic anhydride, and chlorine is passed in.

Title: Improvements relating to servo systems
Inventor: MARTIN DEREK JOHN
IPC: F15B18/00
Filed: 1962-04-17
Abstract: 980,133. Automatic control. FERRANTI Ltd. April 11,1963 [April 17,1962], No. 14804/62. Heading G3R. In a servo-system, two servomotors mechanically coupled in series are. so arranged that when either motor reaches a limiting position in either direction, operation of a switch biases the position of the other motor so as to prevent that motor from taking up a limiting position. In Fig. 1 identical electrical control signals, e.g. in-an aircraft autostabilizer, are applied through amplifiers 9, 8 and 11, 10 to position hydraulic servomotors 1 and 4 which are mechanically coupled in series to actuate an aircraft control surface. Follow-up signals are fed back to amplifiers 9 and 11 from potentiometers 31 and 32 the sliders of which are adjusted by cups 23 and 24 moving with pistons 2 and 4 of servomotors 1 and 4. If, due to a fault, one servomotor piston is moved to a limiting position the other servomotor would move to its opposite limiting position in an attempt to compensate. This is prevented by cups 23, 24 which actuate limit switches 12-15 so that bias signals from sources 25, 28 are applied to amplifiers 9,11 of such polarity that the servomotor which is working properly is moved to a central position. At the same time further limit switches double the gain of the system controlling the effective servomotor so that autostablization is maintained by this servomotor. The error due to the faulty servomotor may either be taken up by the pilot moving his control or, as in a modification applied to an automatic pilot, the error may be eliminated automatically by a further auxiliary servomotor, having a slower response, controlled by additional limit switches. This auxiliary servomotor is automatically maintained in a central position during normal operation. Fault indicators may be provided.

Title: Transport aircraft
IPC: B64D1/02
Filed: 1959-05-01
Abstract: 870,686. Freight carrying aircraft. LEIBER, E. May 1, 1959, No. 14905/59. Class 4. Freight compartment closure means at the rear part of an aircraft fuselage comprises two side flaps 1, a bottom flap 2, and a top cover, forming in the closed position a wedge shaped configuration with a vertical edge pointing towards the rear, the bottom flap being rectangular, to project laterally beyond the side flaps when closed. In the Figure the top cover is formed by the tail boom. When the side flaps 1 are opened to continue the sides of the fuselage, they remain over the bottom flap, and thus an aperture is formed from which freight can be dropped in flight. The bottom flap can be lowered to act as a loading ramp when the aircraft is on the ground, and is fitted with sprags at its rear end, which engage the ground when the flap is lowered to shorten the landing run. The freight compartment may be elongated, and have the rudder on its upper surface and an elevator on each side.

A hoist to allow an operator to deliver goods at varying heights comprises an operator's platform 10 and slave platform 14 which are guided by uprights 3, 4 mounted on a wheeled chassis 1, and are raised and lowered independently by operation of controls 26, 27 on the platform 10. The platforms are raised by single acting hydraulic rams 18, 19 and cables 22, 23, and are lowered gravitationally under the control of one way restrictor valves. If the platform 10 contacts an obstruction when descending a frame 31 is pivoted to the chain line position thereby disengaging a lug 33 from a pin 34 so permitting a spring-loaded bolt 35 to engage a rack bar 37 on the upright 3. In a modification (not shown), the platforms are arranged back to back and at least the operator's platform is provided with embracing side cheeks which engage around the uprights to act as a brace. The two lifting rams are supplied from a common hydraulic source and provision is made for starting and stopping the ascent and descent of the platforms by electrical switches. The ascent of the slave platform is automatically effected by depression of spring- loaded switches beneath the platform by the load. In a further modification (not shown), the slave platform is raised and lowered by an electric motor-driven ratchet-wheel and a chain.

Title: Improvements in circuits employing semi-conductor devices
IPC: H03K3/351
Filed: 1955-05-25
Abstract: 792,120. Semiconductor circuits. GENERAL ELECTRIC CO. May 25, 1955 [May 27, 1954], No. 15129/55. Class 40 (6). In a circuit employing an N-type bar 10 with ohmic base contacts 12, 14 and a P-type junction 16, a diode 74 is included in one base lead biased to conduction by battery 70, the current being defined by resistor 72. Diode 74 operates as a short circuit until the base current exceeds that through resistor 72 so that the saturating region 84 of the curves 80, 81, 84 on the junction current/voltage graph, Fig. 6, becomes the line 82 to define more sharply the intersection with the load line 86. In a triggered mono-stable state circuit, Fig. 7, the circuit described in the Specification is modified by the inclusion of the components 70, 72 and 74. In the quiescent condition the line 77 with a slope equal to the resistance of resistors 50, 52 intersects curve 80 to give the operating point 85. A discharge load line 86 with a slope of the resistance 52 passes through point 85 to intersect the curve 82 at point 87. A positive triggering pulse applied at 62 displaces line 86 to 86<SP>1</SP> above the peak 78 so that current flows in the junction and line 86<SP>1</SP> is followed, the potential falling to point 87 when the input pulse ceases. When capacitor 54 has discharged sufficiently the operating point moves along line 89 to point 83 and then along curve 80 to the quiescent point 85. The change in current due to a triggering pulse is substantially independent of its amplitude. Specifications 786,875, 786,876 and 787,578 are referred to.

Abstract: 544,493. Hydraulic machines. DOWTY EQUIPMENT, Ltd., (formerly AIRCRAFT COMPONENTS, Ltd.), and MACKENZIE, D. Oct. 15, 1940, No. 15304. [Class 69 (ii)] [Also in Group XXXIII] A fluid pressure control system for the actuation of movable elements on aircraft comprises a double-acting jack having its distributing valve controlled electrically by press-buttons from a remote point. Two hydraulic jacks 11 for raising and lowering an aircraft under-carriage are controlled by a valve 7 actuated by a solenoid 8 controlled by a push button on-and-off switch 13, 14 from a remote point. The solenoid is urged by a spring into a position in which the valve 7 puts the upper ends of the jacks 11 into communication with the pressure side of a pump (through the pipes 5, 9). Pressure on the button 13 closes a circuit through the solenoid to cause the valve to put the opposite ends of the jacks into communication with the pipe 5 through the pipes 10. The pump draws fluid from a reservoir 2 through a filter 4. The push buttons 13, 14 are inter-connected to move in opposite directions and have transparent end discs coloured respectively red and green adapted to be illuminated by lamps 13a, 14a. On pressing the button 14 to lower the under-carriage, switches 18 close as actuating arms 20 ori the jack plungers descend and the red disc is illuminated. The light persists until two-way switches 19 are thrown over by the arms 20 whereupon the lamp 13a is extinguished and the green disc is illuminated. When the button 13 is pressed the red disc is illuminated as the jack plungers rise and the lamp 14a extinguished, the lamp 13a also being extinguished when the switches 18 are opened at the top of the stroke. A switch 25 actuated by the engine throttle sounds a buzzer 26 if the throttle is more than two thirds closed before the under-carriage is in its extended position. A switch 27 enables the lamps to be put out of action when not required. The control valve may be mounted on the component to be actuated and plug and socket connections be provided for the electric leads. An example of a solenoid actuated valve is described in Specification 544,340.
